G'day J,

Yes, you can zip together a regular and a long version of the Basecamp BC2.

G'day Aniket,

Thanks for getting in touch, the Basecamp Bc2 is a synthetic model bag, so while it is suitable for multi-day walking it is heavier and bulkier than the TK2 you've enquired about.

G'day Dario,

Yes the difference between the Basecamp BC2 and BC3 sleeping bags is the temperature rating, and therefore the packed size and weight. 

G'day Ann,

Yep, the single comes with a M (14>4.5L) and the double comes with a XL (30>10L) compression sack.

G'day Simon,

LH & RH refers to left hand or righ hand zippers. As this bag is dual zippered though, meaning it has full zips on both sides, the LH & RH isn't applicable.  Thanks so much for picking that up, we'll fix that information!  To confirm, two single basecamps bags will zip together to create a double when needed, however as the bottom of the bag is curved the joint at the bottom wont be quite flush.

G'day Sardo,

The Basecamp Bc2 is a synthetic bag with Thermolite Insulation. The link you provided from Sea to Summit is for the now discontinued Basecamp BCII model which was a down bag. To reduce confusion, Sea to Summit have changed the name and colour of the new model down bag to Explore Ex2. Hopefully, this will help ease confusion. 

G'day Bill,

The Basecamp Bc2 Sleeping Bag compressed bag is correct and packs down to the size next to the Camelbak. There are two separate images next to Camelbak bottles with the larger one being the double size.
